HOISTING AND CONVEYING APPARATUS.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed May 12, 1905. Serial No. 260,185.

To all whom it may concern.-

Be it known that we, THOMAS SPENoER MILLER, a citizen of the UnitedStates, and a resident of South Orange, in the county of Essex and Stateof New Jersey, and J OSEPH H. DIoKINsoN, a citizen of the United States,

and a resident of Montclair, in the county of Essex and State of NewJersey, have invented a new and useful Improvement in Hoisting andConveying Apparatus, of which the following is a specification.

Our invention relates to hoisting and conveying'apparatus of the typeshown in our Patent No. 814,717, dated March 13, 1906, being in thenature of an improvement thereon.

In the accompanying drawings like characters of reference indicate likeparts in all the views.

Figure 1 is a side view of an apparatus containing our invention adaptedfor logging. Fig. 2 is a detail view of our improved duplexload-carriage and the rope connections therewith. .Fig. 3 is a view inend elevation of that portion of the carriage carrying the ropedrum, andFig. 4 is a plan view of the same.

Referring now to the accompanying drawings, 1 and 2 are the head andtail supports, respectively, while 3 is the cable or trackway over whichtravels the duplex load-carriage, (indicated as a whole by O.)

4 is the friction-operated hauling-rope drum of the engine, and 5 is thehauling-rope operated thereby.

The fall-rope of the apparatus is shown at 6 and carries at one end thegripping-tongs 7.

The friction slack-pulling rope drum of the engine is designated by 8,while 9 is the slack-pulling rope operated thereby.

Extending to the tail-support and back again and having its tail madefast to the carriage O is the outhaul-rope 10.

In our patent above referred to the carriage is so constructed that alarge amount of play and flexibility in all lateral directions ispermitted between the two members of the carriage; but in the presentcase we have shown such carriage members joined by a connecting-framewhich embraces a construction found to be preferable in some particularinstances. The present duplex carriage comprises the parts M and M,connected by the rigid frame E, which frame may be of any suitablematerial, such as metal or wood, and is preferably rectangular inconformati on, although, of course, itwill be understood that it may beof any desired shape. The frame we have shown comprises the longitudinal top and bottom side bars 11 and 12, connecting the carriagemembers, while 13 and 14 are straps or plates having their ends bentdownward and outward relative to the main portion of the straps, thelatter being arranged vertically relative to the carriage sides, withthe ends extending beneath the longitudinal connecting bars. At 15 areshown bolts or other fastening means passing through and connecting theside bars and the straps with the carriage sides, while 16 are diagonalstruts or braces adapted to give additional strength and stability tothe frame.

Guide-sheaves 17, 18, and 19 are secured to the head-support, while 20is the guidesheave at the tail-suppoit. 21 and 22 are thetraction-wheels of the duplex load-carriage running on the cable ortrackway, one wheel being carried by each member of the frame, while 22is a small supporting-wheel journaled in the frame portion M of thecarriage and adapted to form a guide andsupport for the main cable.

D is the load-carriage drum, composed of a plurality of parts d, (Z and(i the part d being preferably of less diameter than the parts d and (ZA fall-r0pe pilot-sheave 23 is linked by the clevis 24 with the carriagemember M, so as to have freedom of movement in all directions.

25, 26, 27, and 28 are guide-sheaves journaled on the carriage betweenthe strips 13 and 14 and the sides of the carriage members, such sheavesbeing adapted to steady the opposing run of the outhaul-rope, while 29and 30 indicate idler-pulleys on the part M for the ropes passing aroundthe load-carriage drum.

From the above description the construction of the apparatus will bereadily ap arent, and the operation is substantially as follows:

. When a log is being hauled or lifted by the fall-rope 6, thehauling-rope 5 will be hauled in, and the slack-pullingrope will be paidout under tension by the drums of the engine.

WVhen the fall-rope 6 is being carried out to take a new log, the engineis so operated that the rope 5 is outhauled by the inhaul of the rope10. When the duplex carriage is propelled toward the head-support, theropes 5 and 9 are both inhauled but the speed of the drum 8 issufficiently in excess of the speed of the drum 4 to cause more or lessslip between the friction-surfaces of the frame. The distance of thepilot-rope sheave from the rope-drum D is such as to give a suflicientlyfair lead to the drum part D, upon which said rope is coiled, and thepilot-rope sheave relieves the drum D from the lateral movements andstrains that are encountered in hauling logs from various directions.

The construction of the engine and the operation of the same issubstantially like that described in my copending application abovereferred to, and as this is a well-known form of engine it isunnecessary to here enter into a detailed description of the same. Itwill be noticed that the duplex carriage, such as herein shown anddescribed, embodies the essential and desired features of simplicity,durability, and strength and is of especial advantage in hauling veryheavy loads, such as logs or the like.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

1. In a hauling apparatus in combination two stationary drums, a cableor trackway, a duplex carriage thereon, a rigid frame connecting theparts of the carriage, a rope-drum mounted on one part of the carriageand driven from the stationary drums, and a pilot-sheave mounted on theother part of the carriage.

2. In a hauling apparatus, in combination a cable or trackway, a duplexcarriage consisting of separate members, with a rigid frame connectionbetween the same, a stationary drum mounted outside the carriage, arope-drum mounted on one of said members and driven from the stationarydrum and a pilot-sheave on the other of said members.

3. In a hauling apparatus in combination a cable or trackway, a duplexcarriage comprising separate members, a frame rigidly connecting the twoparts of the carriage, a rope-drum mounted on one of said carriagemembers, a pilot-sheave carried by the other of said members and meansoutside the carriage for driving said rope-drum in opposite directions.
